One of the richest and largest markets in the world, Europe can set global standards. And if a French president is prepared to at least consider clear rules in the Eurozone, then it would be fatal if Germany were not to react.

When it comes to climate protection, the whole world will have to pay the price. But if Donald Trump intends to conclude a trade agreement with the EU, he will have to abide by our climate standards. In any case, waiving climate protection does not make American products more competitive.

Many who have voted for the AfD, or who intend to do so, aren't doing so because they are dyed-in-the-wool enemies of democracy. Rather, they are desperate.

The racist rhetoric that extends all the way to the top of the AfD shows that one must assume that an attitude is prevalent - not just in the grassroots, but also among party leadership - that is not consistent with the basic values reflected in our constitution.

In all of my speeches I talk about why a strong Europe is necessary in order for Germany to be strong over the long term. I think that I have sufficiently shown over the past years that I have a clear notion of how we can make Europe stronger, more democratic and more inclusive. There is really no competition there with Sigmar Gabriel.

Politics is a dynamic process. When I was a young man in the 1970s, Yasser Arafat had just perpetrated various terrorist attacks. Just a few years later, after I had entered European Parliament, the same Yasser Arafat was given the Nobel Peace Prize.

The principles of the SPD have remained the same for 150 years: democracy, human dignity, justice and inclusion. We will never change those principles.
